摘要：

For a scalar delay logistic equation (y) over dot(t) = y(t) (k = 1)Sigma(m)r(k)(t) (1 - y(h(k)(t))/K), h(k)(t) less than or equal to t, a connection between oscillating properties of this equation, the corresponding differential inequalities and the linear equation (x) over dot(t) + (k = 1)Sigma(m)r(k)(t)x(h(k)(t)) = 0, established. Explicit nonoscillation and oscillation conditions are presented. (C) 2000 Elsevier Science B.V. All rights reserved.
